Dry Slipper Clutch Comparison, advice Ducabike/STM/CNC/Yoyodyne models attached

[Qomomoko]

this link is the K-bike slipper I just installed, and mentioned. Its non-adjustible. The adjustible one you posted is different. Why spend $1000  + on an identical Ducabike spider spring slippper? The K-bike 6 spring slipper clutch setup from Nick is about $725 complete with plates. I had the Ducabike one before and it appeared identical to the K-bike slipper one I have now, internally.    
My 2c on the slipper clutches:
  -any slipper will wear out faster than a normal clutch- esp. the plates. I sand them down and remove all glazing about 1/2 thru the plates' life typically.
  -All spider spring slippers appear extremely similar internally, but different shaped pressure plates. I've never had the rest of the clutch (like spider springs or the 6 ball bearings) wear out before the plates do. I get about 15-20k miles out of a complete slipper clutch (ridden hard).
  -I typically have a hard time finding neutral with a brand new slipper clutch setup for the 1st 1 or 2 hundred miles. Then its good.

Makes sense.

Adjustability is a luxury, even a slipper clutch is semi luxury (a tad of safety).

Guess besides the design, there are 2-3 current designs, the next step is type of material/ quality/ quality assurance.

Lb for lb, makes little sense to spend more money. Understanding the lb for lb is what I am doing and getting to.

I am getting some more information from the vendors and will share on this thread.

yeah, I made an account with Kbike, good information and they are organized especially access to instructions/ manuals.
The comparible Kbike IMO to the ducabike 6 spring  comes out to $820 ($900 with taxes and shipping) from black label meccanica.
